PROPYLENE POLYMERS FOR FILMS. |
abstract |
This invention generally relates to crystalline propylene polymers, methods for their production and methods for use in film applications. Specifically, this invention relates to crystalline propylene polymers comprising both propylene homopolymer and propylene copolymer. The compositions are prepared using metallocene catalyst systems comprising at least two metallocenes in a polymerization process that involves sequential or parallel polymerization of propylene homopolymer and copolymer using propylene with a small amount of comonomer, preferably ethylene. The polymerization is catalyzed by a dual metallocene catalyst system. The resulting polymers have a wide distribution of molecular weights, bimodal. The resulting polymers are excellent for use in the production of biaxially oriented films or non-oriented films. Films prepared with these propylene polymers have a significantly broader range of processability or processing capacity and can even be stretched at a lower temperature compared to films prepared from the traditional propylene polymer. |
